Commence rumor mongering! According to the October 2011 issue of
Official Xbox Magazine: "Look for the Fable cycle to continue with
a proper, controller-based Fable IV in 2013 , says The Ball." Now,
it's only a rumor, and a meager one at that, but seeing as how
we're all currently so enamored with the upcoming Fable: The
Journey, further news might be too much for our little hearts
to handle. (Sarcasm)

Microsoft has registered "Fable: The Journey" along with three
other apparent Kinect titles. Rumor has it that MS is planning to
announce these titles during their E3 press conference on the
morrow. Thoughts?

You can see where the domain name has been registered here.

Credit for the find goes to superannuation.

UPDATE: Lionhead's Official Announcement. They've
got a trailer and screenshots.
